It’s incredibly rare for a TV series to last ten seasons, but Supernatural has done just that and is now set to air its milestone 200th episode this coming Tuesday.

Many of Supernatural’s cast and creators, past and present, recently gathered in Vancouver, where the show films, to celebrate the 200th episode. At the event, I spoke to them about the show’s success, its fans and more, including just how much longer the show could go past Season 10.
